“We have not had a terrorist attack on American soil in more than seven years. But we are not safe, as illustrated by the recent attacks in Mumbai,” FBI Director Robert S. Mueller, Wednesday told the Senate Judiciary Committee.

“Our primary threat continues to come from the tribal areas of Pakistan and Afghanistan. But we are seeing persistent activity elsewhere, from the Horn of Africa to Yemen,” he said giving an overview of the “diverse, dangerous, and global in nature,” threats which made terrorism its top priority.

“Global cooperation is not merely the best way to combat global crime and terrorism, it is the only way,” he said.”And we must cooperate not only with our international law enforcement and intelligence partners, but with our
